TYPE-WRITER CARBON-COPY SHIELD.

Specification of Letters Patent.

Patented May 23, 11916.

' Application filed January 7, 1915. Serial N 0. 1,021.

To all whom it may concern:

Be it known that I, ETHEL BRADFORD, a America, and residing at New York, in the county of Kings and State of New York, have invented new and useful Improvements in TypeWVriter Carbon-Copy Shields, of which the following is a specification.

My invention relates to improvements in type-Writer eraser-shields or protectors to be used when erasing and making corrections in carbon copies, single or multiple, without necessitating the removal of the paper from the machine.

The principal object is the construction of-an inexpensive, easily handled and durable eraser-shield or protector to prevent smudging of the typewritten carbon copy when making erasures in the preceding copies.

Another object is to make it impossible for the operator after making erasures in manifold work to accidentally leave any of the members of the protector between the various sheets.

Another object is to construct a shield or protector which can be inserted from either side and which will reach the entire width of the sheet;

Another object is to enable the-operator to quickly and. accurately place the member or'members in any position desired or remove them all at once when desired.

Another object is to construct an erasershield which will prevent the carbon itself from being removed unduly from the carbon sheet when pressed upon by the eraser.

Figure 1, is a perspective view of a portion of a typewriter showing my invention with two of the shield members inserted between the carbon copies ready for use, the original sheet being rolled back, and showing a fragment of one of the members in position at the side when not in use. Fig. 2, is a perspective view showing the device with its plurality'of members partially closed in fan-like formation; Fig. 3, is a longitudinal sectional view of the device.

In the preferred form, the device is composed of a plurality of flexible members such as 4, 5 and 6 each having a curved horizontally extending handle or arm 7. These several handles are hinged together and yieldingly secured by means of an eyelet 8. or similar device. The handles are preferably spaced apart by means of washers 9 interposed between the several handles. This fa cilitates the insertion of the members betweenthe sheets inthe machine. It will be readily-understood from an inspection of Fig. 1 that when only one member of the protector is needed, the others will instantly fall to the side of the machine out of the way of the operator. By leaving the shank 10 comparatively narrow and flexible there is practically no resistance when separating the memberswith the fingers while erasing between the several carbon copies in the machine, and it is easier to keep' the members not in use out of the way. ;The construction of the shank at 10 at the lower edge, permits it to clear the end frame of the machine The device may be constructed of any suitable material, such as celluloid, preferably havin a highly polished surface and of suitable t ickness and flexibility, having substantially noii'v'absorbent, grease-repelling, water-proof surfaces but it should be understood that many variations in form and assembling may be made without departing from the true spirit and scope of my, invention.

The preferred form of the device consists of a plurality of elongated flexible members hinged together in fan-like relation at one end and adapted to be inserted between the carbon copies by simply separating the sheets with the fingers of one hand and dropping the individual protectorsbetween them. This can be done quickly and accurately as soon as the need of corrections arises. In Fig. 1, the sheets of paper are designated 11, 12, 13 and the carbon sheets 14: and 15. In this case the shield members 4 and 5 are placed between sheets 14 and 12 and between 15 and 13 respectively so as to protect sheets 12 and 13 respectively when erasing on sheets 11 and 12 respectively. In manifolding after the erasure on the first page has been made, in order to reach the next sheet'the protector and its carbon copy may be pressed forward by a separating movement of the fingers of the left hand and at the same time the protectors in the rear are held securely against the cylinder adapting themselves to the curved surface of the platen by reason of their flexibility. If it is necessary to make corrections near both margins, the protectors may be collectively moved in or out by means of the elongated handle.

Some of the special advantages embodied an L ' in this simple device will be found in the quickness and ease of inserting the several members between the carbon copies when making corrections while the papers are still in the machine. The form of the protector with its elongated handle allows accurate placing and precludes the possibility of slipping and its flexibility lends itself to the shape of the cylinder. By one movement of the hand the operator may instantly remove all of the protectors thus proving a saving of time and also preventing the possibility of any of the shields being left behind. Where, as in the usual manner, operators use small pieces of paper or cards which are inserted for erasing purposes, one is often forgotten, and after the finished typewritten sheets are removed from the machine a blank space occurs on the copy where the forgotten paper remained. It will be readily understood how valuable time is wasted and unnecessary delay caused by such an occurrence. 7

Although it is preferred to provide a plurality of the elongated members it will be apparent that a very considerable utility is provided by a single member constructed as shown and described;

The protector may be readily cleaned of the carbon adhering to its ,surface by merely rubbing it off with alcohol or an ordinary eraser, thus making it an everready and durable device. The highly polished surfaceremoves less carbon from the surface of the carbon sheet thus making the carbon sheet last longer. The curved flexible shank facilitates the use of the device and allows the unused members to fall readily over the side of the machine.

The ability to make corrections in the typewritten carbon copies while in the machine not only assures accurate and uniform corrections, but the original and carbon copies are as if no corrections had been made.

evident to all competent operators.

\Vhat I claim is 1. An erasing shield for manifold sheets of type-written matter, said shield composed of a plurality of flexible sheetv members having substantially non-absorbent surfaces adapted respectively to be inserted between a plurality of sheets having manifold typewritten matter thereon, and each shield member provided with a handle, said handles being loosely connected at one end to permit the easy insertion of all members and the removal of one member withoutdisturbing the operative position of another member.

2. An erasing shield for manifold sheets of type-written matter," said shield composed of a plurality of flexible sheet members having substantially non-absorbent surfaces adapted respectively to be inserted between a plurality of sheets having manifold typewritten matter thereon, and each shield member provided with a handle, said handles being loosely connected at one end to pershield member provided with a handle, said handles being loosely connected at one end to permit the easy insertion of all members and the removal of one member without disturbing the operative position of another member, said connection comprising a rivet upon which said members swivel.

4. An erasing shield for manifold sheets of type-written matter, comprising an elongated, thin, flexible, broad-bladed paddleshaped shield portion having a flexible horizontally extending handle integral therewith cut out of the lower edge for clearance and for increasin the flexibility adjacent thereto, said hand e constituting means for guiding and moving the shield portion be: tween two manifold sheets of typewritten matter, one surface of said shield being substantially non-absorbent.

5. An erasing shield for manifold sheets of type-written matter comprising, a plu- These various advantages will be selfrality of adjustable members, each member having an elongated handle extending horizontally' therefrom, washers interposed between said members for spacing said members apart and an eyelet inserted through the hole in the ends of the horizontally extending handles of said members for yieldingly securing the parts together.
